IMPROVEMENT IN eMex-MACHINES.

The Schedule referred' to in these Letters Patent and making part of the same.

I. @Hannes W. Fonecsox, of Jackson, Madison county, Tennessee, have invented a new and useful Brick-Machine, ot' which the following is a specification.

Nature and Objects of the Invention.

My inventioncomprises certain devices for drawing the pulver-ized and tempered clay from lthe pug-mill down an inclined plane, and for feeding it into the molds, the construction being such as to permit the escape back onto the-inclined plane of the superfluous clay.

It also comprises a construction o i` molds, whose .top and two sides are movable, by which .means the clay is first pressed with great force, so as to comvpletely fill the mold, and the completed brick is readily expelled therefrom.

Figure 51sa perspective view of the same parts,

without the sliding gate, and with the vertical and horizontal plungers retracted.

Secured to the frame A of the machine isv a shaft, B, having a spuewheel, C, and being operated by a band passing around a pulley, b.

The wheel@ communicates motion, by the pinion e, to the shaft D of a pug-mill, F, within which the said shaft, with its arms d and blades E, revolves, an aperture, f, in the side of the pug-mill conducting the ltempered clay onto an inclined plane or chute, It,

down which the clayis made to pass to .the molds, in the manner hereafter described.

A bevel-wheel, V, onshaft B, gears with a pinion, G, on the shaft g, and this shaft is-providcd with a crank, g', and'pitman, H, which actuate the pressingplunger I, the latter operating on the top of the cla-y contained in the mold J, which mold is divided into a series of compartments by vertical partitions j, so as to permit ot' a number ot' bricks being pressed at the same time.-

The'pressing-plunger I is provided with a number of openings, c', whieh'coincide withl the partitions j of the mold J.

'lhe front of the mold is a sliding gate, K, which, at the proper time, is elevated by the cam g on the shaft g.

rlhe back oi`.the mold is a horizontally-sliding plunger, L, having arack, Z, which gears with a seg wheel, M, or a rock-shaft, on.

The gate K descends by its own weight, aml is confined to avertical path by guides l.' 7o'. i

The rock-shaft on is vibrated at the proper moment by the rods N N', operated b v studs o p, that projectv from t-he wheels O l.

The molds J are supplied with clay in the following manner: v i

filent- R- is'an inclined plaueor chute which' reaches -iroln the molds np lto the bottom of thc pug-mill F, and is vprovided with a scraper, S, which draws the clay down the incline to the mouth of the mold;

The scraper S has a reciprocating movement imparted to it by the connecting rods s s', which are at tached to cranks or wrists t t of the shaft T.

The wheels O I U are driven from bevel-,wheel V bymeans of a bevel-pinion, \V, secured to the inner side of wheel 0.

Operation.

The gate K bei-ngr in its depressed or closed position, the plunger-I being elevated and the plungerL retracted, the follower or scraper S is supplying the mold J with clay, (see iig. 2.)

rlhe rotation of the crank g meanwhile causes the plunger I to descend, thereby lcompressing the clay in the molds.

This is bllowed by an elevation of the gate K and a further advance oi' thc plunger L, so as to expel the bricks from the mold, and to deliver them onto the table X.

The plunger L is nowretracted, the plunger I ele- Y the rack l, segment-wheel M, rockfshattgm, rodsN N Vand studs 0 1), for actuating the expelling-plunger.

In testimony of which invention I hereunto set my hand.
